' Claims. (o1.14o as) This invention relates to a tying machine, andmore particularly to a portable manually operable machine for tensioningand then tying the tensioned band about boxes, bundles or other objects.

This invention will be illustrated and described in its preferredembodiment for applying fiat bands to boxes, but many of the novelfeatures of the invention are applicable to round wire tying machines,and that with slight modifications of the gripping and tying means, theapply round wire bands.

It is an object of this invention to provide a light, portable machinewhich may be handily moved from one box to another, but if desired, maybe mounted relatively stationary and the boxes moved to the machine. H

A further object is to provide the machine with only two grippers one ofwhich may be movable relative to the other, or tensioningfthe, bandabout the box.

means operable serrated surface ofthe first gripper from the therebyinthe band before swinging the gripper to its open position and to therebyprovide a gripper which may be easily actuated and which will not undulymar the portion of the band gripped thereby.

A further object is to provide means for latching the placed band intying position in the machine, and means operable upon the completion ofthe tie for actuating the latch into its open position from whichposition the latch may be either manually or automatically released.

A further object is to hingedly mount the tying for movement to and fromthe tying position, and for utilizing this motion for actuating the bandcutter and crimper, latch release and the means for actuatingthe firstgripper to its open position.

A further object is to provide a band cutter relatively thin bladearranged to receive the first lap of the band between the undersidethereof and machine base, and to be bracedthereby during the severing ofthe surplus portion of the last lap of the band extending over the uppersurface thereof.

A further object is to provide means for operatively retaining therelatively thin stationary cutter blade or tongue in shearing relationwith the movable cutter blade.

A further object is to arrange'the thin sta tionary cutter blade so thatit may be reversed end for end and side for side, whereby as one it isto be understood that machine may be adapted to invention is chosenprincipally for the purpose the jcrimped end cutting edge becomesdulled, the blade maybe turned to present one of the other four edges,andin that way advantageously utilizing the entire blade.

A further object is to provide acrimping means 5 cooperating with themovable cutter blade for crimping the cut end of the bandinto theinitial lap thereof. i

A further object is to provide a simple and effective means foractuating the tying means, and also for maintaining the tying meanslocated centrally over the 'tie during the tying operation.

Other objects and advantages of the invention will become apparent asthe nature of the same is more fully understood from the followingdescription and accompanying drawings wherein is set forth what is nowconsidered to be a preferred embodiment. It should be understood,however, that this particular embodiment of the of exemplification, andthat variations therefrom in details of construction or arrangement ofthe parts may accordingly be effected, and yet remain within the spiritand scope of the invention as the same is set forthin the appendedclaims. j In the drawings: Figure- 1 illustrates a perspective tyingmachine of this invention.

view of the fragmental secview of the j The preferred organizationof thefeatures of be selected and the initial this invention is illustrated inthe drawings as disclosing a portable tying machine which may be easilyand readily moved from one article .to be handed to another.

In Fig. 1 the machine is illustrated as being placed upon the cover of abox 12 at the location at which the band is to be tensioned and tied.The base or frame 13 of the machine may be of such size and shape as tobe firmly and squarely mounted upon the box, provided with appropriatebosses and bearings for operatively supporting the band gripping,tensioning, tying and cutting means thereon.

After the machine has been positioned at the tying location, a band 14of suitable length may end '15 thereof positioned upon the band locatinghorn 16, which horn may be formed integral with or suitably mounted uponthe base of the machine as illustrated in Fig. 1. Next the band may beplaced over the crimping anvil or die 1'1, which die may be mounted uponthe frame or formed integral therewith, and positioned thereon in spacedrelation from the band locating born 16, to provide a band tying zone orspace 18 into which the tying means may be moved.

This first end of the band, may be conveniently referred to as theinitial lap 14a of the band, and, may be next placed over the firstgripper anvil 19, which anvil may be formed upon the machine frameadjacent and in alignment with the crimping die, or may be formed of aseparate piece, (Fig. 6) and suitably fastened thereto.

Means may be provided for securely clamping the initial lap of the bandupon anvil 1 9, which means may include a r pper dog 20 having aserrated gripping surface 21 arranged to cooperate with the anvil tosecurely clamp the band therebetween. The pper dog may be provided witha transverse cylindrical bore 22 of relatively large diameter, andhaving a portion thereof cut-away or stepped as at 23, so as to form thestop shoulders 24 and 25. The bore 22 of the gripper dog may be nicelyjournaled upon the spindle 26 of the gripper dog control lever or driver2'1, which lever may be provided with a transverse bore 28 of lessdiameter and extending through the spindle thereof in eccentric relationthereto for pivotally mounting the said lever upon the machine frame asby means of the pivot pin 29. The lever arm 30 of the gripper driver 2'7may be of such size and shape as to fit into the cut-away section 23 ofthe gripper dog, and may be provided with stop shoulders 31 and 32,arranged to cooperate with the stop shoulders 24 and 25 thereof. It maybe noted from Fig. 4, that when driver 2'1 is rotated with relation tothe gripped dog until the stop shoulder 31 thereof is brought intoengagement with the stop shoulder 25 of the gripper dog, that the stopshoulders 32 and 24 will have been moved apart for a predetermineddistance.

To facilitate the placing of the initial lap of the band within thefirst gripper, the gripping dog 20 may be releasably maintained in itsretracted or open position by suitable gripper control means, whichmeans trated in Figs. 4, 5, and 6, wherein it may be observed that thegripper dog driver 2'1 is provided with a finger 33 adapted to ride uponthe forward end 34 of the lever arm 35, which arm at the rear endthereof, may be pivotally mounted upon the frame as at 36. A forwardlyextending trigg;r 3'! may be pivotally mounted as at 38 to the lever arm35, and may be provided with a cam portion and the base .rnay be movingthe supporting is most clearly illus-- 39 adapted to ride upon the camroller 40 operatively carried by the hinge member 41 indicated by brokenlines in Fig. 6, as the hinge member lies just outside of the plane ofthe sectional view of Fig. 6.

The lever arm 35 may be provided with stop shoulders 42 and 43 forlimiting the travel of the stop pin 44 carried by the trigger andthereby the extent of swing of the trigger.

The hinge member 41 may be journaled upon shaft 45, and may be arrangedto operatively carry the tying means, and said hinge means may beacutated about shaft 45 as a center to carry the tying means to or fromthe tying position. During the swing of the hinge memb ;r while carryingthe tying means from the tying position, the cam roller 40 also carriedthereby, will be brought into engagement with the cam surface 39 of thetrigger, whereby the forward end 34 of the lever arm 35 will be liftedto the position as illustrated in Figs. 4 and 6, to thereby rotate thegripper control lever 2'! in a counterclockwise direction as viewed inFig. 4. The rotation of the gripper control lever will bring shoulder 31thereof into engagement with shoulder 25, to rotatethe gripper dog intoits open position as illustrated in Figs. 4 and 6.

Adjustable spring means may be provided for yieldingly maintaining thegripper control lever in operative engagement with the forward end 34 ofthe lever arm 35, which spring means may include a spring weightedplunger 46 having a semispherical head 4'! bearing in a correspondinglyshaped depression formed in the gripper control lever 2'1,while theopposite end of the plunger may be slidably mounted in a suitableadjusting thimble 48, which thimble may be screw-threaded through theupper portion of a suitable frame bracket, as at 49. The thimble may becounterbored as at 50 to receive one end of a suitable spring 51, whichspring may surround the plunger and act between the inner end of thecounterbored section of the thimble and the head of the plunger toyieldingly urge the gripper control lever 47 to rotate in a clockwisedirection as viewed in Fig. 4.

After the initial lap 14a of the band has been placed within the firstgripper, the gripping dog thereof may be released to rotate under theinfluence of the spring means for securely clamping the band therein. Torelease the gripper, the trigger 37 may be lifted until the cam surface39 thereof will roll of! of the cam roller 40, thus remeans for theforward end 34 of the lever arm 35, whereupon due to the action of thespring means 51, the gripper control lever will rotate in a clockwisedirection.

The gripper dog will follow the rotation of the control lever until theserrated gripping portion thereof will en age the band, whereuponfurther rotation of the gripper dog will be stopped until the stopshoulder 32 of the control lever will have engaged the correspondingshoulder 24 of the gripper dog, whereupon the gripper may befurtheirotated into gripping engagement with the band. It may be well tonote from Fig. 4, that the movement of the control lever with relationto the gripper dog will cause, due to the eccentric mounting of theseparts, the gripper dog to be thrust downwardly in the direction of thegripper anvil, and thus the band may be very tightly clamped in thegripper before or at'about the same time that the trol lever will havereached the stop shoulder 24 of the gripper dog. This latter feature isof more importance during the releasing operation of the stop shoulder32 of the con-- the arrival gripper, as it permits the serrations to belifted substantially out of mesh with the indentations formed thereby inthe band, and thus the rotation of the gripper dog may be made moreeasily as the serrations thereof do not have to cut through thrseindentations as would be the case were the eccentric connection notprovided.

Now that the initial end 14a of the band has been securely gripped inthe first gripper, theremaining portion thereof may be passed under thesecond or movable gripper anvil asmay be observed in Fig. 1, and thenplaced around the box 12 and to appear again as the final lap 14b, whichfinal lap of the band may be successively placed over the initial end ofthe band, carried by the horn 16, over the stationary cutter blade 52,over the serrated gripping 21 of the first gripper, and finally over thesecond gripper anvil 53, and secure y gripped thereon by means of agripper dog 54.

The second gripper anvil 53 may be carried by the reciprocating frame 55(note Fig. 8) of the tensioning means. The frame 55 may be formed in theshape of a U and the gripper dog 54 may be operatively mounted betweenthe two sides of the frame by means of the pivot pin 56.

The gripper dog 54 may have a gripping surface eccentric to the centerof rotation thereof, and also serrated whereby the greater the pull uponthe band toward the right as viewed in Figs.

1 and 8, the greater will be the gripping effect of the dog. A spring 57may act between the gripper dog and frame to yieldingly maintain thegripping dog in gripping relation with the anvil. The gripper dog 54 maybe provided with a thumb piece 58 for manually actuating the dog to itsopen position. However, if'desired, means may be provided which will actto automatically swing the gripper dog to its open position, which meansmay include a U-shaped member 59 of such size as to straddle the gripperdog and to be jourpivot pin 56. The member 59 may be provided with aforwardly projecting portion 60 having a tapered cam surface 61positioned to 'be engaged by the band during the placing of the same inthe gripper for actuating the gripper to its open position.Simultaneously with of the band at its gripping position, it'passesbeyond the influence of the tapered cam surface 61, thus removing themeans for supporting the gripper in its open position, whereupon thespring means 57 will be free to rotate the gripper dog 54 into itsgripping engagement with the placed band.

The second gripper may be mountedfor movement with relation to the framefor tensioning the band about the box, which movable mounting means mayinclude a link 62 operatively connected at one end thereof to one end ofthe gripper frame 55 by means of the pivot pin 56, and at its other endto the machine frame as by a suitable pivot pin 63, while the other endof the gripper frame may be operatively connected to one of the legs 64of the bifurcated tensioning lever 65. The tensioning lever 65 may bepivotal.- ly mounted upon the frame as by the pivot pin 66. and wouldnormally be positioned as illustrated in full lines in Fig. 1 during theplacing of the final lap 14b of the band therein, whereupon by swingingthe tensioning lever toward its broken line position as illustrated inthe same figure, the band may be tightly tensioned about the box.

Means may beprovided to releasably lock the tensioning lever in itsactuated position and therea by retain the tension in the band, whichmeans may include a ratchet 67 (Fig. 8) mounted upon the machine frame,and a cooperating pawl 68 operatively carried'by the tensioning leverand a spring means 69 for yieldingly urging the pawl into engagementwith the ratchet. The pawl may be provided with a handle 70 for theconvenience of releasing the pawl from the ratchet when it is desired toreturn the tensioning lever to its full line-position as illustrated inFig. 1 for the next tensioning operation. A torsional spring -71 maybeprovided for yieldingly urging the tensioning lever to its startingposition, which spring means may be mounted upon the pivot pin 66 andhaving one end connected to the frame while the other end thereof mayengage the tensioning lever as at 72.

Means may be provided for latching the initial and final laps of theband onto the band locating horn 16, which latching means may include alatch lever 74 (Figs. 1 and 3) pivotally mounted upon the machine frameas at 75, and having an angular offset section 76 at the forward endthereof, adapted to latch over the two laps of the band placed over thelocating horn 16 as is clearly illustrated in Figs. 1 and 3, while therear thereof may be provided with a finger 77 against the under side ofwhich the spring means 78 may act to yieldingly urge the latch leverinto band latching position. Means may be provided for normallyretaining the latch lever in its retracted or open position and manuallyoperable for releasing the latch lever as soon as two laps of the bandhave been placed over the horn and automatically actuated during thereturn swing of the tying means to return the latch lever to itsretracted position in substantially the same manner as the first grippermeans is actuated to its open position. For these purposes a trigger 79may be 'pivotally-mounted upon the latch lever and provided with a camsurface 80 arranged to be engaged by a cam roller 81 carried by thehinge member 82, whereby during swing of the hinge member 82 to carrythe tying means to its retracted position, the cam roller 81 carriedtherebywill engage the trigger cam surface, and thus lift the triggerand there by the latch lever to its open position. To release the latchlever for movement into latching position' over the bands, the trigger79 may be manually lifted to swing the trigger cam surface 80 free ofthe cam roller 81, whereupon due to gravity and the action .of thespring means 78, the latch lever will be moved into its latchingposition.

It is desirable but not necessary to manually release the latch lever assoon as the two laps of the band have been placed upon the horn asduring the swing of the tying means into tying position, the cam roller81 carried by the hinge member 82 will be carried out of engagement withthe trigger cam surface, and thus the latch lever may be automaticallyclosed before "the tying operation, and even before the tensionoperation should the tying means be swungto tying position prior to thetensioning of the band.

In Fig. 3 the latch lever and hinge member 82 are illustrated in fulllines in their retracted positions, while in broken lines these partsare illustrated in their closed positions. Note that the cam roller 81,when in its broken line position, is well away from the broken lineposition of the trigger cam surface.

Thelatch lever 'may be provided with stop shoulders 83 and 84 againstwhich the pin 85 carried by the trigger, may engage for limiting theswing thereof.

The band now having been latched and tensioned, the next operation willbe the forming of a secure tie in the overlapping portions of theinitial and flnal'laps of the band at the tying none 18.

The particular form of tie is not a feature of I this invention, and maybe of 'anysuitable style, preferably as disclosed in my Patent No.1,677,522 issued July 1'7, 1928.

The tying means by the hinge members ferred to, which hinge naled uponthe shaft means may be swung position.

The tying means may include, as illustrated inFlgs. 1and2,apairoftyingjaws86and87 pivotally interconnected by the pivot pin88, and each jaw carrying one of a pair of cooperating tying dies 89operable for forming a tie 90 in the placed band, (note Fig. 10).

Thefree end of the tying jaw 86 may be bifurcated to receive between thebifurcations thereof, the actuating or operating lever 91, while thefree end of the tying jaw 87 may be bifurcated to receive between thebifurcations thereof, the actuating or operating lever 92. The operatinglever 91 may be pivotally connected to the tying jaw 86 as by means ofthe pivot pin 93, while the operating lever 92 may be similarlyconnected to the tying jaw 87 by means of the pivot pin 94, and as maybe most clearly observed in Pig 2, the inner ends of these actuatilevers may be connected to the cros head 95 as by means of suitablepivot pins 96 and 9'1. To insure the imiform actuation of the operatinglevers, a sectoral gear means 98 may be formed upon the inner end of theopera lever 91 concentric with the cross head pivot pin 96 thereof,while a corresponding and meshing sectoral gear means 99 may be formedupon the inner end of the operating lever 92 concentric with the crosshead pivot pin 9'1, whereby the actuation of one lever will cause anequal but opposite motion of the other lever. The free end of theoperating lever 91 may be provided with a handle 100 while the operatinglever 92 may be provided with a handle 101, (note Fig. 1).

It is desirable to moimt the tying means upon the hinge members 41 and82 to permit the swingin thereof to and from the tying position, so asto move the said tying means out of the way during the band placingoperation. The tying means may be pivotally mounted upon the hingemembers 41 and 82 by means of the pivot pin 93, as is clearly shown inFig. 1, and to maintain the tying jaws in correct tying alignment withthe band, the crosshead 95 thereof may be provided with a crosshead pin102, which pin may project from each side of the croshead and each endthereof nicely fit into the crosshead slots 103 formed in the hingemembers.

be normally maintained illustrated in Fig. 1, during the band placingoperation, and either prior to or after the tension operation may beswlmg to the tying position as illustrated in broken lines in this samefigure. After the band has been sufliciently tensioned, the handles 100and 101 may be actuated to closethe tying dies uponthebandtoformthetiethereinsuchas illustrated in Fig. 10. The position which thediiferent'parts of the tying means will assume may be operativelycarried 41 and 82, previously remembers be jour- 45, whereby the tyingto and from the'tying spring means 113, which spring at' the completionof the tie forming operation, is illustrated in Fig. 2.

Upon the completion of the tie forming operation, the handles may bereturned to their broken line position as illustrated in Fig. 1, andthen the entire tying means swung to the open or retracted position, asillustrated in full lines therein. The

its fully retracted rearwardly motion thereof.

Itisduringtherearwardlyswingofthetying means that the cam rollers 40 and81 carried by the hinge members engage the latch and gripper means foractuating these parts to their open or retracted positions.

Thisrearwardswingofthetyingmeansmay also be utilized for actuating theband cutting and crimping means. The band cutting and crimping means areclearly illustrated in Figs. 1 and 7, and may include the stationarycutter blade or tongue 52 anda movable cutter blade 105. The stationarycutter blade 52 may be formed of a flat strip of tool steel ofrelatively thin section, and may be relatively loosely mounted in thecutter groove 106 formed in the frame, and each end of the. stationarycutter blade may be provided with a locating hole 107, through which thepoint 108 of the screw 109 may project for correctly locating andretaining the stationary blade within the frame groove. As may beobserved from Figs. 1 and 7, the stationary blade 52 is symmetrical inall respects, and therefore may be turned end for end or side for sidein order to make possible the utilization of each of the four cuttingedges thereof, whereby a single blade may have along life. As may benoted in '7, the forward end of the stationary cutter blade overlies thecrimping anvil or die 1'7 sufliciently for the initial lap 14a of theband to be inserted therebetween, thus the relatlvely thin stationarycutter blade will be solidly braced dining the cutting operation.

As the stationary cutter blade overlies the crimping anvil or die 17sufficiently for the initial lap 14a of the band to be insertedtherebetween and because it projects outwardly from the machine basemore or less in the fashion of a tongue and to more clearlydistinguish-this blade from the movable cutter blade, it may be referredto hereinafter as the superposed cutter tongue.

The movable cutter blade may be pivotally molmted in the frame cuttergroove 106 as by means of the pivot pin 110, and upon the forward endthereof may be formed the shearing edge 111 adapted to cooperate withthe stationary blade for severing the final lap of the band adjacent thetie formed therein. In order to positively retain the forward end of thestationary blade in cutting relation with the shearing edge 111 of themovable blade, the movable blade at the forward end thereof may beprovided with a depending lug 112 arranged to engage the side of thestationary blade opposed to the cutting edge thereof prior to theengagement of the shearing blade 111 with the band. The lug 112 may beso proportioned as to latch over the placed laps of the band and tothereby also act to retain the band portions in correct severing andcrimping positions.

The movable cutter 105 may carry a suitable means may act to yieldinglyretain the stationary cutter blade in its operative position and topermit the staing anvil.

7 atively joumaled upon the hinge shaft 45 and- F pin 110 and to thusswing tionary blade to be slightly lifted during the placing of theinitial lap of the band upon the crimp- The means for actuating themovable cutter blade may include a ratchet-cam wheel 114 operhavingpreferably four ratchet-cam teeth. The ratchet-cam wheel may bepositioned directlyto the rear of the movable cutter blade and themovable blade may be so shaped as to opcratively engage the wheel insuch relation that the cam surface 115- of the blade may ride over-thecam surface 116 of the wheel during the rotation thereof to cause theblade to rock about its pivot the shearing. edge 111 thereof across thestationary blade and thereby sever the final lap of the band placed overthe stationary blade.

The ratchet-cam wheel-114 may be rotated a quarter of a turn during theswing of the tying means from its tying to its retracted position, byproviding the hinge member .41 (Fig. 7)' with a pawl 11'! adapted toengage the ratchet face 118 of one of the ratchet teeth when the tyingmeans is moved to the tying position, and thus to rotate the ratchet-camwheel during the return swing of the tying means to its retractedshearing edge 111 of the r 105 may be made removable crimp the cut endposition. v

A spring means 119 may be provided for yieldingly urging the pawl 117into operative engagement with the ratchet-cam wheel,'and a stop pin 120may be provided for limiting the swing of the Y pawl under the influenceof said spring means.

The cam surface 115 of the movable cutter blade by providing a separatecam block '121 appropriately mounted upon the rear end of the blade asby suitable screw means 122. The cam block 121 and the ratchetcam wheelmay both be made of steel and hardened, but even so, there may be somewear between these parts which may be compensated for by providing shimsof suitable thickness between the cam block and movable blade. Also bythis arrangement the action of the cutterblade may be nicely adjustedwithin relation to the crimping die. Y Y A band crimpingmeans may beprovidedto of the final lap 14b ,of the band into a depression formed inthe initial lap thereof, whereby the cut end will be lodged below thenormal surface of the band and therefore will not catch upon other boxeswhen piled one upon an-' To crimp the cut end of the tie, the crimpinganvil 17 may be provided with a crimping groove 123 (Figs. 2 and '1)positioned directly below the and the movable cutter movement to drivethe cut end of the; final lap of the band together with the adjacentportion of the initial lap thereof into the crimping groove 123, andthus crimping the band as illustrated in Fig nw, as at 124. Y

The operation of the machine may be-briefiy summarized as follows:First, the machine may be positioned upon the object to be tied, at thelo-- cation at which the band is to be placed therearound; second, theplacing of the band which operation may be briefly restated as follows;the initial end thereof placed upon the band locating,

I It may be noted especially in Fig. 7, that during the swing of thetying means to its tying position,

that the movable cutterlever 105 will act as a in this figure.

From the above description it will be appreciatedthat the tyingoperation may be accomplished easily, quickly andefiect'ively.
